Product Summary

A gearbox is a device which converts speed and torque, whereas a transmission is a type of gearbox that can be "shifted" to dynamically change the speed: torque ratio, such as in a vehicle. The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and anywhere else rotational speed and torque needs to be adapted.

The marine industry uses high performance ship gears and gearboxes in a variety of vessels including fast ferry boats, luxury yachts, frigates and work boats etc. These ship gear boxes are generally much more powerful and complicated than the non-marine counterparts.

Ship gearbox is available in a variety of configurations and specifications to meet critical applications. The selection of a gear and gearbox is made keeping in mind factors including gear geometry, speed, load and operating temperature among other considerations. These gearboxes are specially designed for maximum mechanical efficiency with the casing being strengthened with ribs for making it as stiff as possible.
